Welcome to the full online version of the Panamath software.

Panamath measures your number sense and Approximate Number System (ANS) aptitude. After answering a brief set of questions about yourself, you will complete the Panamath test. On each trial of the test, a brief flash of yellow and blue dots will appear, and you will respond whether you think there are more yellow dots or blue dots. At the end, you will see an output of your results and how you stack up compared with others who have taken the test.
